What This Type of Project Involves

Room additions are a broad category that span everything from constructing a new bathroom to full second-story additions. At their foundation, room additions require adding to your home's footprint — either outward. This is distinct from remodeling, which stays inside the current square footage.

These projects require a collaborative approach that involves architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions involve multiple building disciplines, choosing a general contractor who can oversee every step is the key to a smooth project.

Room additions are a great fit for homeowners who have outgrown their current layout but prefer to stay in place. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the work follows a structured set of steps that our team have refined over many years.
